Lumbar Facet Injection

Date: March 7, 2022

What Is a Lumbar Facet Joint?

Lumbar facet joints are sets of tiny joints between the vertebrae located in the back of the spine. The joints have opposite cartilage surfaces, which restricts frictions between the bones.

The synovial fluid surrounds the joint and acts as lubrication to further limit friction between the bones that rub together.

Healthy facet joints will support your spine, allowing you to twist and bend easily. However, your joint can become very painful and heavily inflamed due to various medical conditions such as trauma from car crashes, spinal stenosis, or degenerated discs.

Lumbar facet joint injections are frequently used to help in the diagnosis of the source and location of discomfort, as well as to provide pain relief.

Numbing medicines are injected into the facet joints to determine whether or not the facet joint is causing the patient’s suffering by studying the patient’s immediate pain decrease.

Is a lumbar facet injection the same as an epidural in terms of effectiveness?

Procedures may be stressful, but if you know what to expect, this information will help you plan ahead of time. You’ll also be more prepared for your therapy if you do your homework beforehand.

Preparation for the procedure

  • Plan a ride home with a friend or loved one ahead of time. After obtaining an anesthetic or taking pain medication, you should not drive.
  • Become familiar with the exact operation being performed, as well as the risks, advantages, and other alternatives available to you.
  • It’s detrimental that your doctor knows about all of the medications and natural remedies you’re using. Several drugs might make the surgery more dangerous, but your doctor will tell you whether to quit any of them before surgery, as well as how soon you should discontinue them.
  • If you are currently taking aspirin or another blood thinner, consult your doctor to determine whether you should discontinue use prior to your treatment. It’s crucial that you understand everything your doctor has asked you to do.
  • Confirm that your doctor and the hospital know your advance care planning. For those who have not yet put one together, you should consider doing so. It’s a wise precaution before undergoing surgery or medical treatment. It tells others what kind of care you’d want to get.

Following the procedure

When the numbing drug wears off, and the cortisone starts to act, patients may suffer a transient increase in discomfort that lasts several days.

It is common for doctors to suggest the following treatments throughout the week following an injection:

  • If the area is uncomfortable for the first two to three days after receiving the injection, gently applying ice or a cold compress to the general area of the injection site will sometimes relieve discomfort.
  • After completion of the therapy program, patients can take their standard pain medication
  • After treatment, patients should be able to return to their everyday routines.
  • Patients may be referred for physical or manual therapy to ensure that the anesthetic and/or cortisone are working correctly. In order to verify if the cortisone is working as intended, this might extend for several weeks or even months.
  • The next day, if the soreness has reduced, it is advised that you resume your regular exercise and activities in moderation. Even after significant pain relief, it’s critical to gradually increase activity levels over one to two weeks to avoid the risk of recurrence.

  2. Patients will be instructed to lie face on their stomach to begin the process. Preparation of the injection site and application of a topical numbing agent will be performed before giving the local anesthetic.
  3. Fluoroscopy, commonly known as a live X-ray, is usually used to perform a lumbar facet injection. Generally, this accurately guides the doctor to target the correct place to insert the needle.  
  4. After the needle is in place, anesthesia and steroids are injected into the facet joint using a fluoroscopic tracer.
  5. The steroid reduces inflammation and irritation, while the anesthetic relieves pain and discomfort.
  6. Once in the spine, the combination drug works its way down to the lower levels and segments, reducing inflammation and irritation.
  7. Now, the needle will be removed, and the injection site will be bandaged with gauze.

Following-procedure care

  • Pain scores would have been taken at the time of the surgery and will be retaken around 15-20 minutes following the procedure.
  • At least 20 minutes after the incident occurs, keep an eye out for any immediate concerns. The patient should record a daily pain diary for the next two weeks as a reminder.
